During the suppression operation against Eight Fingers, Lockmeier teams up with Climb and Brain Unglaus. During the reconnaissance, he finds out that all of Six Arms are gathered at their destination. Fortunately, Sebas Tian joins them, allowing them to get inside and rescue Tsuare rather than fighting. While Sebas kills four of Six Arms without injuries, Lockmeier, Climb and Brain Unglaus encounters Zero and Succulent. Lockmeier is badly wounded by Zero's attack, but overcomes the crisis by the help of a healing potion. He later supports Climb to defeat Succulent.
After the appearance of Jaldabaoth, Lockmeier volunteers to help Climb and Brain even though he knows that their mission is extremely dangerous. Fortunately, he returns safely after the mission.

As one of Marquis Raeven's private troops, Lockmeier alongside with his comrades joined the annual war at Katze Plains. During the Massacre, Lockmeier alongside with his comrades tried to buy time for Marquis Raeven to escape but he and the rest of his comrades were all killed by the Dark Young.
Being a former Orichalcum ranked adventurer, Lockmeier was skilled in stealth and disarming traps. His own combat capability was low, but he can support his colleagues by using various items.
Marquis Raeven was Lockmeier's employer and superior in his private force. Raeven appreciates his services, and when he and his team die, the Marquis suffers great grief.
Lockmeier teams up with Climb during the suppression operation. Later he volunteers himself to help him again during the events of the Demonic Disturbance. Climb reminds him of his younger days. He respects his decisions and thinks no one has the right to force him off from his path.
He teamed up with Brain in the suppression operation to help Climb. He both cares for and respects Brain.
- (To Brain about Climb): "How shall I put it seeing a kid like him fight so hard made me remember the days when I was still young, even if it was just for a while. I think I understand how you feel about this too. Even so it was the path he chose. We have no right to force him off it."
